Nylon 12
Nylon 12 is the most flexible and toughest nylon in dry conditions. When saturated in water, it becomes stiffer and more rigid than all other nylons.
What is Nylon 12?
Nylon 12 is the most flexible and toughest nylon in dry conditions. When saturated in water, it becomes stiffer and more rigid than all other nylons. Whether wet or dry, it has the lowest abrasion. The crystallite melting point is lower than that of other nylons, giving nylon 12 the lowest heat distortion temperature and softening point. It resists high impact at low temperatures when dry but nylon 6 and 6,6 have better impact resistance when wet.
Nylon 12 is a copolymer and gets its name from the twelve carbons donated by each monomer.
We extrude Nylon 12 for single-lumen, multi-lumen, bump and co-extruded medical tubing. See how it compares with the other grades on our nylon tubing page, or ask us which nylon suits your device.
Nylon 12 questions, answered
What is the melting point of nylon 12?
Typical melting points for nylon 12 grades on our datasheet are 257°F (125°C) to 590°F (310°C). Its glass transition temperature is 207°F (97°C) to 378°F (192°C).
What is the tensile strength of nylon 12?
Tensile strength at break for nylon 12 runs 2,180 psi (15 MPa) to 4,930 psi (34 MPa), with elongation at break of 500%.
What is the density of nylon 12?
Nylon 12 has a specific gravity of 0.0343 lb./in.3 (0.950 g/cc) to 0.0444 lb./in.3 (1.23 g/cc), which corresponds to a density of about 0.950 to 1.23 g/cm³.
How hard is nylon 12?
On our datasheet, nylon 12 grades measure Shore D 40 to 88.
How can nylon 12 tubing be sterilized?
Depending on grade, nylon 12 is compatible with steam. Confirm the method for your specific grade with the resin supplier.
